3D Printing for Surgical Planning | Part I
As the utilization of 3D Printing and additive manufacturing continues to disseminate amongst a number of industries, medical 3D printing has seen some of the most rapid grown. 3D-printed anatomical models for surgical planning and clinical training have a wide array of applications in the hospital inpatient setting. Coupled with the benefits, they have fueled a growing clinical interest in surgical applications, as indicated by the number of published papers addressing 3D printing’s use in preparation for surgical cases.This application of 3D Printing is rapidly gaining popularity, with more journal publications from 2015 onwards than all previous years combined. Over the next few weeks we'll be taking a look at the ins and outs of this leading-edge medical application. This week, we'll be overviewing some of the benefits 3D-printed anatomical models bring to clinical and outpatient settings.
3D Printing: Promoting Precision Medicine
The benefits of 3D printing result from the clarity provided by patient-specific anatomical models that illustrate structure and pathology, which may be vague, obscure or hidden in X-ray, computed tomography (CT), magnetic resonance imaging (MRI) or ultrasound images. The information communicated by a physical model translates to numerous advantages starting with better insights, which leads to better outcomes, both clinically and economically.

Furthermore, these models enable clinicians to clearly communicate with patients, improving over previous 2D modalities. By facilitating patient understanding, patient-specific, 3D printed anatomical models help promote improved complaince and informed consent.In published pilot studies, the main benefits can be categorized intro three main categories:
Holding an exact replica of a patient’s anatomy allows the surgical team to be better prepared before entering the operating room (OR). The model presents the pathology that may reveal a solution or possible complication that could not be seen when evaluating a 2D representation. These plans can then be easily communicated with patients, providing a common ground for communication. The models also help explain potential complications or functional outcomes related to anatomical limitations.
Depending on a 3D printer's ability to match the clinical environment, the model may be used to practice a procedure that involves one or more medical specialties. This can better prepare the team to address risks and difficulties, resulting in more efficient procedures and improved outcomes. Furthermore, 3D printing can be combined with other modalities for hyper-realistic training scenarios.
Rapidly gaining adoption is the use of patient-specific models to determine viability of procedures, appropriate selection of a surgical approach and/or device, and compare alternative strategies/devices by practicing on patient-specifc examples. The surgical team may ascertain that an entirely different approach is required or that a more suitable device would better accommodate the patient. This also allows surgical teams to assess potential complications and plan for them accordingly, before even stepping foot into a surgical theatre.
Case Example | Double Aortic Arch
Following the diagnosis of a double aortic arch in young Mia Gonzalez, the challenge was determining a surgical plan to save her life. Dr. Redmond Burke, director of pediatric cardiovascular surgery at Nicklaus Children’s Hospital, said that with a 3D model of her complex aortic arch vessels. Dr. Burke attributes the 2-hour reduction in Mia’s procedure to the 3D printed model, and the smaller incision resulted in a faster recovery than is typical in these procedures. Furthermore, the model used by Dr. Burke to plan the procedure was also used to explain the current condition impacting Mia's quality of life, and the the surgical plan that Burke's team intended. After years of unsuccessful diagnosis, this new approach was like a breath of fresh air for Mia and her family.
